To all whom it mag concern Be itknown thatI, WILLIAM CAvE, a citizen of the United States,'residing at Newell,

V in thecounty of Buena. Yista and State of s Iolwa, have invented certain new and useful Improvements Surface-Cultivators,- of

j which the following is aspecification, refer- -ence being had-to the accompanying. drawings. 7 v

This invention relates to certain improvements in surface cultivators of a wheeled type and hasrelation more particularly to a v fidevice of this general character where n bothknives and rakes are employed; and 1t .App'licat ion filed seftem erisgieis, SrialiNol51,395.

gularextremityQ of. the arm A an d whereit will bejperceive'd that the arms A and :B will be operatively engaged with the head 1-1; The -.,outer extremities of the arms A iandgB terminate in the annular members or Specification of :IiettersPatent; I Patented A eyes 5 between whichis adapted to bejposi eyes 5'and-Q6isadapted-to be disposedthe 15 is an object of the invention to provide novel ancl'improved means whereby a knife and a coacting rake may be voperatively engaged with the machine in such a'manner as to per-' mit a convenient adjustment of the pitch of 2 0 the knife and an adjustment ofthe rake Trelative tothe row. 1- f The invention consists in the detallsof construction and 1n the combination and arjwithathe longitudinally disposed slots 10 1 a 1 sgo the; surface knife K of well .tioned theannular member. or eye-6 sofl the 1 arm Gandthrough'said annular members-or knowntype. The annular membersor eyes 5 and 6;. have threaded therethrough the clampingscrews7 whereby an effective engagement is :had with the shank S. j v

. It is to be; observed that the arm B com prises tworsections 8 and 9, the adjacent extremities whereof being in overlying relationand one offlsa-ld "sections. 1s provlded through which is adaptedto be disposed the clamping: bolts 11' carried by the section 8; 7 I

v By this;arrangement, it will be seen that rangement of the" several parts of my im- 7 proved surface cultivator whereby certain important advantages are attalnedandzthe device is rendered simpler, less expensive.

and otherwise more convenient andsadvan' tageous for use, all as will be hereinafter more fully set forth. 1 J The novel features of the invention will becarefully defined in theappended claims.

' In order that my invention may be the better understood, 1 will now proceed to describe the same with reference to the accompanying drawings, wherein- Figure 1 is a view in perspective illustrating an embodiment of my invention, the cogiven'to the knife-:Ka I

I 12-1denotes 'an elongatedarm havingone the arm'B may "be lengthened or shortened in accordance with the pitch desired to be .extren aity' v pivotally engaged with thehead 1 Hintermediate the length thereof and hav- .ing its opposite eXtremity; -11nderlying ythe A arm C normally disposed laterally relative e j to the arms AandB, and said arm C is pm, -1-vided withmth'e longitudinally;disposed z lelongated slot 14 through-which is disposed acting portion of a cultivator being shown 40 in fragment; and Fig. 2 is a detail fragmen- A tary sectional view illustratingcertain features of my invention as herein embodied.

As disclosed in the accompanying drawing, H denotes a head of the type employed in the well known tower two-row cultivator, the rear extremity of which being provided with an opening 1 therethrough in which 7 is adapted to be inserted from above the angular extremity 2 of the arm A, said extremity being preferably disposed at right angles to the arm. Also insertible within the opening 1 of the head H is the upstanding boss 3 carried by an'extremity of the arm B, said boss being adapted to have disposed therethrough the headed volt 4 adapt ed for detachable engagement with the anone-of the clamping bolts 15 for operatively rake B being also of a well known type. By

engaging the'rake R with the arm 12, said the'provision of the elongated slot 14; in the arm C, it will be readily observed that the position of the rake relative-to a row'jmay be adjusted as will best meet the requirements of practice. s

It is also preferable to have operatively engaged with the head H, in'a' well known manner, a forward knife K.

From the foregoing description, it is thought to'becbvious that a surface cultivator-constructed in accordance with my inventlon isof'an extremely simple and comparatively inexpensive nature and is .particularly welladapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and spirit thereof and for this reason I do not as V wish to he understood as limiting myself to the precise arrangement and formation. of

1,111; combination with a cultivator in? eluding a head provided with an opening therethrough, an arm having 1 an angular extremity disposed within said opening, a

second arm having a lateral extension disposed within the openingthrough the opposite side of the head, both of said arms being arranged substantially. parallel to. the line .cluding a head provided; with an opening of draft, means coacting. with the extensions ofthe arms for. maintainingsaid arms operatively engaged withthe head, and a ground engaging implement operatively supported by the outer extremities ofthe arms-T 2. In combination with a cultivator ineluding ahead provided with. an. opening therethrough, an arm having, an angular extremity disposed within said opening from one side of the head, a second arm having a lateral extension disposed within the opening through the opposite side of the head, means coacting with the extensions of @the arms for maintaining said arms, operatively engaged with the head, and a ground engaging implement operatively supported by 'the outer extremities of the arms, .one of said arms being capable of longitudinal adjust ment. g V I 3.
